| 目的 在军校大学生中进行中文版坚毅量表（Grit-12）的信度、效度检验，为研究大学生坚毅水平提供可靠的测量工具。方法 对原版Grit-12的条目进行翻译和回译，初测调查337人，采用SPSS 21.0软件对条目进行验证，形成正式的中文版坚毅量表。正式施测调查997人，其中201人采用SPSS 21.0软件进行探索性因素分析和信度检验，796人采用Amos 17.0软件进行验证性因素分析且同时施测心理资本量表（PCQ-24）进行效标效度检验。此外，随机从正式施测的796人中抽取47人在2周后进行重测。结果 中文版坚毅量表由12个条目组成，12个条目的因子载荷均不低于0.56，累积方差贡献率为47.54%。验证性因素分析结果表明模型拟合较好，χ2/df=2.31，比较拟合指数（CFI）为0.97，Tucker-Lewis指数（TLI）为0.94，拟合优度指数（GFI）为0.97，增值拟合指数（IFI）为0.97，近似误差均方根（RMSEA）为0.05，均方根残差（SRMR）为0.06；中文版坚毅量表总分及2个分量表得分与心理资本总分及分量表得分均呈正相关（P均<0.001）。总量表的Cronbach’s a系数为0.83，2个分量表的a系数分别为0.76和0.82。总量表的重测信度（相关系数）为0.80。结论 修订后的中文版坚毅量表具有良好的效度和信度，可以作为测量军校大学生坚毅水平的适宜工具。 |

| Abstract: |
| Objective To test the reliability and validity of the Chinese version of Grit-12 in military college students, so as to provide a reliable measurement tool for studying grit levels of college students. Methods The items of original Grit-12 were translated and back-translated to survey 337 participants in primary test, and were verified by SPSS 21.0 to form the official Chinese version of Grit-12. A total of 997 students were formally surveyed with the Chinese version of Grit-12, in which 201 students were assessed for exploratory factor analysis and reliability test using SPSS 21.0 software; 796 students were assessed for confirmatory factor analysis using Amos 17.0 software and for validity test by psychological capital scale (PCQ-24). After 2 weeks, 47 of 796 students were retested. Results The Chinese version of Grit-12 included 12 items, and the factor loading of each item was over 0.56. The accumulating explanatory rate of the 12 items was 47.54%. Confirmatory factor analysis showed that the Chinese version of Grit-12 had a good construct validity, with χ2/df=2.31, comparative fit index (CFI)=0.97, Tucker-Lewis index (TLI)=0.94, goodness of fit index (GFI)=0.97, incremental fit index (IFI)=0.97, root mean square error of approximation (RMSEA)=0.05, and square residual mean root (SRMR)=0.06. The total score of the Chinese version of Grit-12 and the scores of subscales were positively correlated with the total score of psychological capital and subscale scores (all P<0.001). The Cronbach α coefficient of the Grit-12 was 0.83, and the α coefficients of the two subscales were 0.76 and 0.82, respectively. The retest reliability (correlation coefficient) of the Chinese version of Grit-12 was 0.80. Conclusion The Chinese version of Grit-12 has good validity and reliability, suggesting that it can be used for assessing grit levels of military college students. |
